Re: shell_exec - asynchronous would be cool!

German Geek napsal(a):

Hi all, A while ago, i had a problem with shell_exec: I was writing some code to execute imagemagick to convert a bunch of images. This could take ages to execute and the page therefore ages to load. The solution was to get a linux box and append a & at the end to do it in the background or make a ajax call to a page that does it in batches. The problem was really that i had to write a file that is then checked against to know when it was finished... Not very pretty. Anyway, would it be possible to make a "new" shell_exec_async function in php that just starts the process, puts it to the background and calls a callback function or another script with parameters when it finishes? I guess a callback function is not really going to work because the page needs to finish execution. It should be possible with PHP forking though. Anyway, just an idea.

I would exec a script on linux (=> multi-thread). That script would do anything what is needed (imagemagick) and then check if there are any processes running on the same session. If NOT than it would call (could be HTTP request also) a PHP script on the windows server. What's the deal? Martin
